I started reading ham radio magazines, on a monthly basis which came out exctly 50 years ago. This month's issue: The 73 Magazine from June 1970: https://ia800702.us.archive.org/27/items/73-magazine-1970-06/06_June_1970.pdf
Finally managed to install the antenna switch in the attic. For controlling it remotely, I use an old Arduino with Ethernet shield. Since the antenna switch needs 12V for triggering its relais, a 4 channel relais module is needed to convert the high signal from 5v to 12v. The Arduino takes simple HTTP GET requests for choosing the desired antenna. Now I can switch to any antenna from the shack via the network without a dedicated control cable 👍
Just look at this beautiful hand crafted QSL card! It’s also very special because it confirms my first Hell (rag chew) QSO with a very nice OM. Thank you Eric, F4FAP! #hamradio
New project: raspberry pi controlled remote antenna switch. One remote rpi for triggering the 4 relais inside the antenna switch and one rpi connected to the TRX in the shack measuring the ATU port's voltage to fully automatically choose the correct antenna for each band. Let's see how this works out :)

What are your thoughts? How would you log from fldigi and flwkey to Cloudlog?
Had fun last night making a shortened 30m dipole based on the calculations of OE1MEW. If everything goes well, I’ll be QRV on 30m this weekend 😊 #hamradio
